KNOCKDC JWN CONCRETE BUILDING.

To all :whom it may concern:

Be it known that I, WALTER C. BROUGH- TON, a citizen of the UnitedStates, residing at Kansas City, in the county of Jackson and State ofMissouri, have invented certain new and useful Im rovements in KnockdownConcrete Buil ings, of which the following is a specification.

My invention relates to improvements in knock-down concrete buildings,and one obj ect is to provide a building of this character which may bemanufactured at a central .plant and shipped to any point ready to beset up for use. Y

The invention and in fact buildings of all description, and in orderthat the inventionmay be fully understood, reference will now be made tothe accompanying drawings, in which: J

Figure 1 is a perspective view of the invention in the [form of agarage. Fig. 2 is a broken plan view of the same, partly in section.Fig. 3 is a broken verticalsection on line HI-III of Fig. .2. Fig. 4 isa detail perspective of one of the wall slabs of the building. Figs. 5and 6 are perspectives of metal pilasters employed in uniting the wallslabs. Fig. 7 is a detail of a dowel pin used in carrying out theinvention. Fig. 8 is a broken cross section on line VITIVIII of Fig. 2.Fig. 9 is a detail of a wall with modified means for uniting the severalslabs thereof. Fig. 10 is a horizontal section on line XX of Fig. 9.Fig. 11 is a side elevation partly in section of two wall slabs withanother modified form of means for uniting saidslabsf Fig. 12 is an endview of the structure disclosed by Fig. 11. Fig. 13 is a side elevationof two wall slabs with still another modified form of means for unitingsaid slabs. Fig. 14 is a horizontal section on line XIV-XIV of Fig. 13.

In carrying out my invention, I employ any suitable number of wall slabs1, each having marginal grooves 2 at its upper and lower ends. Each slab1, is enlarged at its lower portion 3, which presents a broad foundationfor the slab to rest upon, and also aids in giving a panel efiect to thecompleted wall, as shown on Fig. 1.

4 designates tie-rods extending through 1he upper and lower portions ofeach wall ilab tdreinforce the same and assist in unitmg the wallslabswhen setting up the buildng. The protruding ends of the tierods 4 isadaptable to private Specification of Letters Patent. Application filedApril 28, 1913. Serial No. 763,051.

are threaded to receive nuts 4*. If the roof of the building is to slopeas shown on Fig. 1, the upper margins of the wall slabs 1 are beveled asshown on Figs. 3 and 4, so that the weightof the roof slabs 5 will beequally distributed upon the front and rear corners 6 and 7 of saidupper edges.

The roof slabs nal edges to form grooves 8 into which a filler isdeposited to render the joints between said slabs rain-proof. The jointat the ridge of the roof is closed by a concrete slab 9 which slopes inopposite directions to conform to the pitch of the roof. The slabs 5rest at their higher ends upon a metallic rldge-pole 10, which in turnrests upon the end walls as shown on Fi tions of the roof slabs whichrest upon the side walls have depending dowel pins 11 with heads 12 attheir lower ends, which enter openings 13in the upper ends of the wallslabs 1. Openings 13 are slightly larger at their lower than upper endsand are filled with plastic cement just preparatory to lowering thedowel pins 11 therein, which push the surplus cement out of saidopenings 13 and the remainder of the cement becoming embedded thereinabove the heads 12 firmly holds said dowel pins from upward movement. Asimilar arrangement may be employed to secure the upper ends of the roofslabs 5 to the ridge-pole 10, so that said roof slabs will be firmlyanchored to the walls of thebuilding, making the same cyclone proof.

14 designates a metal pilaster arranged, preferably, in the form of achannel bar provided at its three sides with holes 15 and 16, throughthe former of which the projecting ends of tie-rods 4 are passed toreceive the nuts 4* which, together with said tie-rods bind thepilasters and wall slabs firmly together. After the pilasters 14 havebeen set up in position, the outer face of each is covered by a concreteslab 17 secured thereto by nuts 18 and bolts 19, which latter have theirends embedded in slab 17 and project through the holes 16 to receive thenuts 18. (See Fig. 2.)

The wall slabs 1 adjacent the corners of the building are secured tocorner pilasters 20, each arranged, preferably, in the form of anangle-iron, having holes 22 to receive bolts 23. The ends of bolts 23are embedded in triangular corner concrete slabs 24:, while theirthreaded ends project through holes 22 and metal plates 25, which latterbear g. 2. Those por-' against the two adjacent slabs 1. The threadedends of bolts 23 are provided with nuts 26, the screwing up of whichdraws the corner slabs 24 firmly against the two adjacent wall slabs 1.The longitudinal edges of the slabs 17 and 2.4 overlap the edges of theadjacent wall slabs 1, to make the intervening joints air and watertight. The walls of the building as shown in the present instance, restupon a concrete floor 27.

As the walls of the building are erected, the grooves with cement asshown on Fig. 3, to render the joints between said wall slabs, the roofslabs, and the floor air and water tight.

In the modified form shown on Figs. -9 and 10, each wall slab 1 isprovided with tubes 4* instead of the tie-rods 4. Tubes 49 are arrangedin alinement with each other to receive a tie-rod 4 which extendsthrough all the sections of the wall or as many sections thereof asdesired, and also through angle-irons 20 which are firmly drawn towardeach other and clamp the wall slabs 1 to ether when the nuts 5 arescrewed upon said tie-rods 4.

In the modified form disclosed by Figs. 11 and 12, each wall slab 1 isprovided with a plurality of tubes 4 and 4*, some being arrangedhorizontally and, some vertically. The smaller tubes l 'project from oneside of their respective slabs as shown on Fig. 11 to enter the largertubes of the abutting sleeves, after which the whole are tightened bytie rods 4* and nuts 43 In the modified form disclosed by Figs. 13 and14:, the wall slabs 1 are separated by intervening pilas ters 14, eachhaving a plurality of tubes 49 to receive the projecting ends of tubes 4embedded in the wall slabs,

the whole being drawn together by rods 4 and. nuts 4 From the foregoingdescription it is ap- 2 of the wall slabs l, are filled arent that Ihave prbduced a knock-down uilding which can be readily set up for useand when once in position is practically non-destructible.

While I have shown my building in the form of a garage, it is obviousthat it can as readily be made in the form of a dwelling having doorsand windows at any point in the walls thereof.

Having thus described my invention, what I claim and desire to secure byLetters Pat- 4 ent is:

1. In a building of the character described, end walls and side walls,angle bars at the corners of said walls, said angle bars having holestherein, tie members extending through the walls and the holes in saidangle bars, means toengage said tie members to lock the whole together,corner slabs abutting the angle-bars and overlapping the, adj acent endsof the walls, plates abutting the inner corners of the walls, and boltsem-.

bedded in the corner slabs and secured to said plates, substantially asdescribed.

2. In a building of the character described, a plurality of wall slabs,tie-members extending through said wall slabs and projecting therefrom,channel-bar pilasters interposed between the wall slabs and providedwith holes to receive the projecting ends of the tie-members, saidchannel-bar pilasters being unobstructed at their rear sides and havingtheir front sides set in from the front sides of the wall slabs, andconcrete slabs removably-secured to the front sides of the channel-barsand overlapping the adjacent sides of the wall slabs.

In testimony whereof I afiix my signature, in the presence of twowitnesses.
